My hon. Friend is absolutely right. In fact, I was speaking with my Canadian counterpart in Montreal on Thursday. The Canadians suffered an appalling loss of life, and they are leading some work on visas and the repatriation of bodies. We are working together with them, all those affected and, indeed, our wider partners to ensure a credible, full and transparent investigation, because although we understand that Iran has accepted responsibility, we still do not know why the incident happened and all the details of how it happened. For the British victims, the Canadian victims, the Ukrainian victims and, above all, the Iranian victims, we deserve to know the answers to the questions and the truth behind why this appalling avoidable tragedy happened.
